FOLDING BOX.

Specification of Letters Patent.

Application filed August 20, 1914. Serial No. 857.730.

To all whom it may concern Be it'known that I, Gnxxxno DRAMIS, a subject of the King of Italy, residing at Brooklyn. in the county of Kings and State of New York. have invented certain new and usefulImprovements in Folding Boxes; and ldo hereby declare the following to be a full. clear. and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fold ng boxes,

preferably to be made of paper and provided with simple. reliable and eilicient means for locking the sides with the ends or for looking a cover upon the box, said box being cut from a fiat blank without material waste and the locking tongues and slots for receiving the same being on the coincident radial line.

. Another object of the invention is to pro-. vide locking means for the sides and ends of paper boxes, said locking means being of simple construction and being easy to engage and reliable and not liable to becomedetached when engaged.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which I igure 1 is a plan view of a portion of a box blank and showing the locking means for one side and one end of the box. Fig. '2 is a view looking fronr the inside of a box toward one end during the process of uniting the sides and ends of the box by the locking tongues, and Fig. 3 is a view looking at the inner side of the ends of the box with the. tongues engaged in their respective slots. and the side of the box being shown in section.

Referring to the drawing. the numeral 1 designates a bottom of a box, and 2 is one end portion of the box, and 3 is one side of the box.

The numerals 4 and 5 designate parallel horizontal slots in the end 2 of the box and (i is a vertical branch of the slot 4.

The numeral designates the extended portion of the side 3 on which the locking tongues are formed. The locking tongue 8 is designed to engage the slots 4 and (3. and the tongue 9 which is formed on a coincident radius from the slot 5 is adapted to engage the said slot. The tongue 9 is provided with a curved edge 10 on the outer side and a reversely curved edge 12 upon the innerside. The radius a.-Z) is struck from the center 11 and extends from the outer edge of the slot 'l' tothe end of the tongue 8. A radius ccZ extends from the opposite end of the slot 4 to the base of the tongue 3. The

radius c extends from the outer portionof the slot 5 to the top and terminal portion of the tongue 9. while .the radius g-h extends from the opposite side of the slot 5 to the base line 12 of the t ngue 9-. and terminates at the point 19', and said curved line 12 leads from the corner point 20 to the point.19. The tongue 8 is provided with a plain edge 13 whichterminates at the outer corner 18. The point of entrance 17 of the tongue 8 is slightly cut away in Fig. 1, said tongue having a plain lower line '15 formed by the inclined line 16 which is formed by cutting away a triangular piece at this point. lVhen the side 3 is folded up. the corner :20 is inserted in the slot 5, and when the tongue is entirely inserted as shown in Fig. 2, the

point 17 of the tongue 8 is in position to be/go inserted in the slot 1. and when said tongue 8 1s fully inserted. the side and end of the box is firmlylocked in position and cannottongues can be readily inserted by merely folding the box on the scored lines thus 'bringing the tongues in proper coincidence with the. slots 1 and 5.

Various changes may be made in-the de tails of construction without departing from the spirit and scope of the invention as de-. fined in the claims.

\Vhat is claimed is V 1. A folding box comprising a bottom side and end walls. said end wallsprovided with superposed slits. each upper slit having a downwardly extending slit formed therewithand communi ating with the inner end thereof. the end walls and side walls provided with locking tongues. said locking tongues being formed by cutting away portions of the side walls forming an upper and lower tongue. the lower tongue being adapted to engage the lower slot thereby limiting thev downward movement or inward movement of the side walls at thesame time-Jilin tongue limits the outward movement of the same and holds the box is position.

2. A folding box including side, bottom and end walls, said end walls having superposed transverse slits therein, upper slit having a downwardly extending slit com inunicating therewith at itsinner end, said locking tongues formed side walls having thereon, locking tongues being so formed that they are positioned one above the other, the lower tongue projecting outwardly from the side thereof, the upper tongue extending vertically from the lower tongue having a rearwardly extending curved portion cutaway forming a V-shaped slot, the lower tongue adapted to engage the lower slit on the inward movement of the side limiting the inward movement thereof, the upper tongue engaging the rear downwardly extending slit by inserting the upper tongue through the upper slit and pulling the side outward, whereby the box will be held in an assembled position.

In testimony whereof I afiix my signature in presence of two witnesses.
